The results show that hydrodynamic dispersion and indigenous biodegradation under mixed electron accepter conditions are primary mechanisms for the attenuation of ethanol and BTEX in porous media.
The 'hot' dispersion equation of the coaxial ridge-disk-loaded cylindrical waveguide TWT with an annular electron beam can be firstly obtained according to self-consistent field theory.
引入薄环形电子注，首次建立了脊加载同轴膜片圆波导的注波互作用线性理论，得到小信号条件下的色散方程。
